Digital image encryption algorithm through unimodular matrix and logistic map using Python

, 2021
Hill Cipher is one of the methods used in Cryptography. In the Hill Cipher algorithm, the key square matrix must have an inverse modulo. One special matrix that definitely has an inverse is the unimodular matrix.

A refinement of the logistic map for cryptographic applications

Franklin Open
This paper proposes a one-dimensional chaotic map that is a refinement of the well-known logistic map. The proposed map exhibits chaotic behavior over a much wider domain for its control parameter compared to the logistic map.

Adaptation to the Edge of Chaos in the Self-Adjusting Logistic Map

, 2000
Self-adjusting, or adaptive systems have gathered much recent interest. We present a model for self-adjusting systems which treats the control parameters of the system as slowly varying, rather than constant.

Sequential inverse problems Bayesian principles and the\ud logistic map example [PDF]

, 2010
Bayesian statistics provides a general framework for solving inverse problems, but is not without interpretation and implementation problems. This paper discusses difficulties arising from the fact that forward models are always in error to some extent ...

A logistic map approach to economic cycles I. The best adapted companies

, 2004
A birth-death lattice gas model about the influence of an environment on the fitness and concentration evolution of economic entities is analytically examined. The model can be mapped onto a high order logistic map.

Building Logistic Spiking Neuron Models Using Analytical Approach

IEEE Access, 2019
Spiking neuron models are inspired by biological neurons. They can simulate the neuronal activities of the mammalian brains, such as spiking (integrator) and periodic oscillation (resonator).

Recurrence Plot Based Measures of Complexity and its Application to Heart Rate Variability Data

, 2002
The knowledge of transitions between regular, laminar or chaotic behavior is essential to understand the underlying mechanisms behind complex systems. While several linear approaches are often insufficient to describe such processes, there are several ...

Spatiotemporal chaos in Arnold coupled logistic map lattice

Nonlinear Analysis, 2013
In this paper, we propose a new spatiotemporal dynamics of Arnold coupled logistic map lattice (ACLML). Here, the coupling method between lattices is not a neighborhood coupling but the non-neighborhood of Arnold cat maps.

Renormalized entropy for one dimensional discrete maps: periodic and quasi-periodic route to chaos and their robustness

, 2013
We apply renormalized entropy as a complexity measure to the logistic and sine-circle maps. In the case of logistic map, renormalized entropy decreases (increases) until the accumulation point (after the accumulation point up to the most chaotic state ...
